unexpected pregnancy 😭

My baby is only 5 months old. I've been using an IUD and felt safe... until suddenly I felt nauseous after eating my husband's homemade omelet. Sure enough, I'm pregnant again 😭 I'm thinking of terminating this pregnancy because I'm not ready for another child. I'm experiencing quite severe baby blues. Just thinking about it makes me want to run away. But my husband says not to terminate it, because a child is a blessing from God. I'm really angry with my husband. I'm confused about what to do now... Does anyone have any advice?
